Steam enters a nozzle at 400°c and 800 kpa with a velocity of 10 m/s, and leaves at 300°c and 200 kpa while losing heat at a rate of 25 kw. for an inlet area of 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit.

606 m/s

Explanation:

Given

Steam Inlet temperature and pressure 800 KPa

initial Velocity 10 m/s

Steam Outlet Velocity is and pressure is 200 KPa

From steam table

Heat loss 25  KW

inlet area 800 cm^2

applying Steady Flow Energy Equation

and volume flow rate is
